Write-*Log CmdLets do not support pipeline input

[mamidenn]

I would like to be able to pipe the output of CmdLets or called programs into Write-*Log. Currently, only the last element of the input gets actually logged.

New-Logger | Add-SinkConsole | Start-Logger
'Foo', 'Bar', 'Baz' | Write-InfoLog
Close-Logger

Expected:

[13:37:00 INF] Foo
[13:37:00 INF] Bar
[13:37:00 INF] Baz

# Or

[13:37:00 INF] Foo
Bar
Baz

Actual:

[13:37:00 INF] Baz

This is due to the CmdLets using ValueFromPipeline for the $MessageTemplate parameter but not wrapping the execution body in a Process block. Basically, all that needs to be done is replace this

Write-Log -MessageTemplate $MessageTemplate -Logger $Logger -Exception $Exception -ErrorRecord $ErrorRecord -PropertyValues $PropertyValues -PassThru:$PassThru

with this in all the CmdLets:

Process {
    Write-Log -MessageTemplate $MessageTemplate -Logger $Logger -Exception $Exception -ErrorRecord $ErrorRecord -PropertyValues $PropertyValues -PassThru:$PassThru
}

I can open a PR if you are interested in this.
Also big props for this nice project 👍.

hi again Martin, you rock 👍 thanks for fixing this
saw your PR, I'll fix the pipeline(yes, it fails because of unrelated issue) and then I'll merge it in.

I have some unfinished changes in PoShLog, so I will release your fix when I'm done.

Hi, I've relesed 2.2.0-preview1 to test some changes. You can verify your bugfixes there👍
Thanks again 🥇
